Compare Intermedia SIP Trunking vs. Sansay VSXi Software SBC

Upgrading your on-premise business phone system through SIP Trunks not only enhances flexibility but also reduces telephony expenses. You can either modernize your current phone infrastructure or save enough to invest in a brand-new system. Most contemporary phone systems seamlessly integrate with SIP Trunking without any need for additional hardware. Our Partners collaborate closely to facilitate all aspects of setup and migration. Reduce your costs with lower rates for long-distance, toll-free, and international calls. By utilizing Intermedia's robust enterprise-grade data centers, you can safeguard your operations against local outages. Traditionally, customers incur costs based on a per-line charge for physical phone lines originating from their central office, leading to significant expenditures. The initial investment is substantial, and the costs associated with adding more lines for growth can be prohibitive. However, SIP Trunking allows phone calls to be transmitted over the internet, fundamentally changing the cost structure and flexibility of business communications. This shift not only streamlines operations but also positions businesses for future scalability and efficiency.
